MITAB Library overview
======================
Note: until there is good complete documentation for the MITAB library,
this README file is the only source of information for integrating the
MITAB library in your application.

USING THE TAB2TAB CONVERSION PROGRAM:
-------------------------------------
MITAB comes with a conversion program called TAB2TAB that can do tab-to-mif
and mif-to-tab translations:
Usage: tab2tab <src_filename> <dst_filename>
Converts TAB or MIF file <src_filename> to TAB or MIF format.
The extension of <dst_filename> (.tab or .mif) defines the output format.
COMPILING THE LIBRARY:
----------------------
When you extract the ZIP (or .tar.gz) file, you will get 3 directories
and the makefiles to compile the library using VC++ 6 under Windows or
using GNU make and GCC on Unix.
The MITAB directory contains the core of the library and the TAB2TAB
conversion program.
The OGR and CPL directories are support libraries used by MITAB and probably
won't be of much interest to you at the beginning.
To compile the lib on Windows:
In a DOS prompt, setup the VC++ environment variables by executing
VCVARS32.BAT (somewhere in your VC++ install) and start the build
using:
nmake -f makefile.vc
This should automagically compile the 3 sub-directories and the test
program (tab2tab.exe, tabdump.exe, mitabc_test.exe) in the MITAB directory.
If you plan to use MITAB from Visual Basic or non-C environments, then
have a look at contrib/README_VB.TXT
To compile the library on Unix:
The main directory contains a GNUmakefile whose default target will
compile the contents of the 3 sub-directories and the test programs
in the mitab directory.
Note about byte ordering: by default, the library is built for systems
with LSB first (Intel) byte ordering. To build the library on systems
that use MSB first byte ordering (such as SUN systems), you should add
the "-DCPL_MSB" flag to the compile flags in the "GNUmake.opt" file.
USING THE LIBRARY IN YOUR PROGRAMS:
-----------------------------------
There are 2 interfaces to access the library:
1- The C API. The C API is a simplified interface which allows you to
build simple applications quickly but may not give you access to every
property of every object type.
See the C API documentation on http://mitab.maptools.org/
There are also interface definition files for various environments
in the contrib directory (mainly VB, Pascal and MapBasic... thanks to
Bo Thomsen)
2- The C++ API will give you full access to every feature of the MapInfo
data model. Unfortunately there is no complete documentation for the
library's C++ classes yet, but tab2tab.cpp is a good example that
shows how to open TAB files for read and write. Also, the main
classes you will need to deal with live in the header MITAB.H.
The rest of this file covers mostly the C++ API features but may also apply
to the C API indirectly.
TO READ FILES:
--------------
To open a .TAB or .MIF file for read, you can use the static method:
IMapInfoFile *IMapInfoFile::SmartOpen(const char *pszFname,
GBool bTestOpenNoError);
This function returns NULL if the file cannot be opened. If the open
was succesful, then it returns a new object of the type corresponding
to the type of file that was opened:
class TABFile: Class to handle .TAB datasets for read/write access.
Note that you cannot use it to modify exsiting datasets
(not yet!).
class TABView: Class to handle views on pairs of .TAB files linked
through an indexed field of type integer.
class MIFFile: Class to handle MIF files for read/write.
The method IMapInfoFile::GetFileClass() can be used to establish the
type of object that has been returned by SmartOpen().
TO CREATE NEW FILES:
--------------------
For write access, you create an instance of TABFile or MIFFile and use
it to open the new file and write to it. Note that only sequential write is
supported.
FEATURE CLASSES:
----------------
On read access, GetFeatureRef() returns object of classes derived from
class TABFeature. You can tell the type of an object using the method
TABFeature::GetFeatureClass().
The following table lists the various feature types and the geometry
types that can be returned and that are accepted (for writing) by each
of them:
Feature Type Returns (read mode) Accepts (write mode)
